Answer:
972 u³
Step-by-step explanation:
The radius is 9 . We can use formula ,
⇒ V = 4/3 π r³
⇒ V = 4/3 × π × 9³
⇒ V = 4 × π × 81 × 3
⇒ V = 972 unit³
<h2>Solution (a) :-</h2>
Quantity of flour needed to make 20 pancakes =



Then , number of pancakes that can be made from 1 cup of floor :-



.
Therefore , 12 pancakes can be made from 1 cup of floor .
<h2>Solution (b) :-</h2>
Number of pancakes that can be made with 1 cup of flour = 12 pancakes
Number of pancakes that can be made with 9 cups of flour :-
= 9 × 12
= 108 pancakes
Therefore , I can make 108 pancakes with 9 cups of flour .
<h2>Solution (c) :-</h2>
Yes , I have enough flour to make 100 pancakes . I say this because :-
With one cup of flour I can make = 12 pancakes
With 9 cups of flour I can make =
= 9 × 12
= 108 pancakes
As I can make 108 pancakes with 9 cups of flour , I can conclude that I have enough flour to make 100 pancakes .
